Was wondering if these will work? http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=7297816&CatId=3670 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=458906&CatId=3670 http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=582798&CatId=3670 |

Was wondering if these will work? Made those links clickable, yes they'll crunch Seti, but not fast, you'll need an external fan blowing some air across them too. Claggy |

Was wondering if these will work? Made you links active. Never mind, Claggy beat me to it :D Steve Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website |

Will they be so slow that if they render one cpu core inactive, I will be worse off? |

slow as molasses you better off finding something a lil more expensive like a 400 series card don t cheap out on the vid card there s a reason they are so cheap this is nice http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=41125&CatId=3585 I came down with a bad case of i don't give a crap |

The GT 430 is a nice little card with 96 cuda core`s, i have the PCI 512MB (not PCIe) version and is the only thing i am crunching with, so my RAC that you can see under my name is what this card can do, i only put it on seti a few weeks ago and so my rac is still on the way up. The PCIe 1GB types will be a little quicker. |

Will they be so slow that if they render one cpu core inactive, I will be worse off? Normally no, the GPU task just reserves part of the CPU core, and a CPU task can run on the rest. But, not sure which of 6 hosts you're planning to use the card on, so let us know which host in case there's a unique problem. You have a 210 on one host 4380299, but haven't run a GPU task on it. Why not try it out and see if it works and if it is "as slow as molasses" before you buy another. Do you have a setup problem, or concerns, or ???? http://setiathome.berkeley.edu/show_host_detail.php?hostid=4380299 As to model suggestion, you've got some good ones so I won't add to those. You might want to spend some time to do an advanced search in NC for the model you're looking at to see what people say about it.

Cards that work with SETI, nVIDIA likes to call CUDA (enabled) cards. Here's a list (Scroll down to GeForce list) http://developer.nvidia.com/cuda-gpus And here is another link you might need now, or in the future: http://www.nvidia.com/object/graphics_cards_buy_now.html Ignore the fact it says "buy now". What you're interested in here is the Relative Compute Performance column. It's only a "rough guide", but accurate enough. PS If you really do have a 210, I think that's pretty much the same card as my ION. It should be ok for an RAC of 800-1200. Be patient though, it takes about a week or two for any new hardware to show it's full potential RAC-wise. Happy crunching! |

Thanks for all the suggestions. I'll have to look into why my 210 series card is not crunching. Thought I had enabled GPU crunching. |

Thanks for all the suggestions. I'll have to look into why my 210 series card is not crunching. Thought I had enabled GPU crunching. According to the Application details for host 4380299, that host has only done CPU MB tasks, and it's the same with your 8400 GS host, you're eithier not installed the Cuda app, or you're got 'Use Nvidia GPU' deselected in your Setiathome project preferences, Claggy |

Thanks for all the suggestions. I'll have to look into why my 210 series card is not crunching. Thought I had enabled GPU crunching. Well, I believe I have done all those things. I suspect my 8400 gs doesn't crunch because it only has 256 meg ram, and about 50 meg is used for actual video, so it falls under the minimum needed. yesterday I updated the driver on my gt210 but it didn't seem to make a difference. On that rig, BOINC shows that it is GPU enabled when I hover over the boinc systray icon...which it did even before I updated the driver. At this point, I don't know if my problem is simply the fact that there is no work. Strangely enough, in the event log, it shows that the gpu requests work from R@H, but not from Seti. |

Thanks for all the suggestions. I'll have to look into why my 210 series card is not crunching. Thought I had enabled GPU crunching. If you have the Cuda app installed, Boinc should ask for Nvidia GPU work, unless you're got 'Use Nvidia GPU' deselected in your Seti project preferences, if you haven't got the Cuda app installed Boinc 6.12.34 will Never ask for Nvidia GPU work. In Boinc Manager, if you go to the Projects Tab, then click on the SETI@home project, then click the Properities Box, Does it say 'Don't fetch Nvidia GPU tasks'? Claggy |

The host with the 8400 may need some other work fetch troubleshooting. It was down to 2 tasks yesterday when you and Claggy swapped notes (he beat me of course.) Project was out of work then, but had been sending some work prior to that, and your other hosts weren't that dry.

On my 8400 GS rig, among other things, it says...GPU scheduling priority 00:00 GPU work fetch priority 00:00 GPU work fetch deferred for 3:32:21 GPU work fetch deferral interval 5:20:00 Thoughts? |

I suspect my 8400 gs doesn't crunch because it only has 256 meg ram, and about 50 meg is used for actual video, so it falls under the minimum needed. With a 256 MiB reporting 235 MiB you won't get stock. You would get tasks if you selected the CUDA app in the Lunatics installer (and got the settings on the preferences page right) - but as stated on the selection screen a minimum of 230 MiB free VRAM is required to run. If not enough free RAM is detected on startup, the current x38g will do CPU fallback (you don't want that!). So unless you can free up some more video RAM on that host, you can't use the 8400 for crunching SETI. [Collatz needs less RAM if you are looking for something to run on that GPU] Right now, there is no work, so even if your 210 is set up right, it can't get any - it should be asking though. Rosetta doesn't have a GPU app and AFAIK neither has CPDN. Check the projects tab -> seti -> properties entry. It should have some numbers in the 'priority' and 'deferred' fields. If you see 'Project preference - Don't fetch NVIDIA GPU tasks' you have disabled the GPU in the server preferences page |

On my 8400 GS rig, among other things, it says...GPU scheduling priority 00:00 If he's got any 'GPU work fetch deferral', then he's asked for work and got none. I'm afraid the next stage takes you into Event Log territory. |

wow, I am impressed with all the super fast attempts to help me get my gpu started. Thanks. I'm virtually certain that I do not have the gpu on my 8400gs rig disabled or deselected, and AFAIK, I did the Lunatics install properly. In fact Boinc reports GPU is enabled. I have tried to reduce my video ram being used, but to no avail. I tried reducing screen resolution...but I don't know what else to do. Googleing is no help. If you have any suggestions in this regard...??? I am not able to check my GT 210 right now, but I will tomorrow. |

On my 8400 GS rig, among other things, it says...GPU scheduling priority 00:00 Here's some log. For the first time ever, I see a Seti GPU request.
